Sleep/Wake Options for Jetson Nano 2GB

Hello! I’ve read that the Jetson Nano 2GB does not have deep sleep capability in previous posts.

For my project, I need to be able to power down the board at night to preserve solar battery power.

Are there any options to put the board into low power mode that will not wake on anything but a RTC Alarm?

Is this still an issue to support? Any result can be shared? Thanks
